Local consumption of remote services

Abstract

An approach for providing simulated remote services locally. A local virtual access module collects remote services for local virtual service access. Service information associated with the remote services is collected to create local service packages. A network tunnel is created on firewalls where the remote services are accessible by associated local service packages. Local environment variables are created to establish local virtual service access and the local virtual service access module simulates cloud service access outside a cloud environment.

Description

BACKGROUND OF THE INVENTION

The present invention relates generally to developing, testing and deploying cloud applications and more particularly to consuming a cloud service when an on-demand cloud application is not deployed on a cloud.

During cloud application development, an application can be created and compiled using tools such as, but not limited to, an integrated development environment (IDE). An IDE can consist of source code editor(s), build automation tools and debugger. Cloud application development can be a demanding process as cloud services are important to the function of a cloud application. Cloud services can provide foundational and complementary function to cloud applications within in a cloud environment. Cloud services are architected to operate in a cloud environment and are generally not directly visible and/or accessible outside the cloud environment due to factors such as, but not limited to, security and access policies. To manage the life cycle of cloud applications, a Software Developer can perform an installation and configuration of cloud services in a local environment, creating local and stand-alone cloud services from a “real” cloud environment. When “local” stand-alone copies of the cloud services are established in a plurality of local environments, application development, testing and debugging can be performed with a risk that the local service does not operate exactly as “real” cloud service.

SUMMARY

As disclosed herein, a method for providing simulated remote services locally, the method comprising: collecting, by one or more local virtual access modules, one or more remote services for local virtual service access; collecting, by the one or more local virtual access modules, one or more service information associated with the one or more remote services; creating, by the one or more local virtual access modules, one or more local service packages; creating, by the one or more local virtual access modules, a network tunnel on one or more firewalls wherein the one or more remote services are accessible by the one or more local service packages, respectively; creating, by the one or more local virtual access modules, one or more local environment variables wherein the one or more local environment variables are configured to provide the local virtual service access and simulating, by the one or more local virtual access modules, the one or more remote services based on the local virtual service access. A computer system and a computer program product corresponding to the above method are also disclosed herein.

FIG. 1 depicts a cloud computing environment according to an embodiment of the present invention.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth and active user accounts). Resource usage can be monitored, controlled and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring to FIG. 1, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C and/or automobile computer system 54N may communicate. Computing nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public or Hybrid clouds as described hereinabove or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 1 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

FIG. 4 is a flowchart depicting simulated local cloud service environment setup and operation, in accordance with an embodiment of the present invention.

In step CREATE SERVICE PACKAGE 402 of flow diagram 400 simulated local cloud service flow, SERVICE PACKAGER 330 can collect the logic of SERVICE(S) 304 and associated authentication rules from AUTHENTICATION PROCESSOR 308 to create an associated SERVICE PACKAGE 324. The selection of SERVICE(S) 304 to be packaged for virtual access (e.g., simulated cloud access) can be predetermined by methods such as, but not limited to, a user selection, a predetermined list and an automated scan of APPLICATION(S) 332 code components to create a collection/list of services used. Each SERVICE PACKAGE 324 can comprise a plurality of SERVICE(S) 304 (e.g., one to many) function provided association of SERVICE PACKAGE 324 and SERVICE(S) 304 are not discernable to APPLICATION(S) 332 and/or IDE 334 operation. SERVICE PACKAGER 330 can provide a recording component for storing sync transactions while LOCAL VIRTUAL ACCESS MODULE 322 operates in off-line mode.

In step CREATE TUNNEL 404, LOCAL VIRTUAL ACCESS MODULE 322 enables/creates a network tunnel between VIRTUAL SERVICE MODULE 96 and LOCAL VIRTUAL ACCESS MODULE 322 and/or COMPUTER SYSTEM 320. The network tunnel establishes a virtual link between SERVICE(S) 304 and associated SERVICE PACKAGE 324 to make SERVICE(S) 304 visible remotely (e.g., outside of a cloud).

In step DEBUG SESSION 406, a debug session is started using a tool such as, but not limited to, IDE 334. Access information is configured to access a cloud service in a local environment. It should be noted that IDE 334 configuration can be established within IDE 334 or by other techniques such as, but not limited to, injecting environment variables in COMPUTER SYSTEM 320. At completion of step DEBUG SESSION 406, IDE 334 recognizes SERVICE PACKAGE 324 as the associated real SERVICE(S) 304.

In step AUTHENTICATE 408, APPLICATION(S) 332 can be operating by IDE 334 and/or locally to access various SERVICE(S) 304. SERVICE(S) 304 can require authentication to determine if access is permitted and what kind of access is permitted a user and/or an application has with SERVICE(S) 304. In off-line mode, SERVICE PACKAGE 324 provides simulated authentication. In on-line mode, the same authentication component of SERVICE PACKAGE 324 can be used where LOCAL VIRTUAL ACCESS MODULE 322 sends authentication information toward AUTHENTICATION PROCESSOR 308.

Step OFF-LINE 410 can be a logical option that can be enabled for purposes such as, but not limited to, isolated debugging of APPLICATION(S) 332 where, for example, a user may desire delayed, limited or no transaction information to pass to a cloud environment. Embodiments of the present invention can provide an off-line mode switch for control by a user and/or predetermined settings. Off-line mode can be a selection applied to a plurality and/or combination of SERVICE PACKAGE 324 based on implementation. When off-line mode is enabled, operation flow proceeds toward step RECORD SYNC 412, otherwise, operation flow proceeds toward step PROCESS SYNC 414.

In step RECORD SYNC 412, a recording of operating actions can be activated during off-line mode. If SERVICE PACKAGE 324 is accessed during APPLICATION(S) 332 testing, a record of actions can be sent toward SYNC STORE 326. For different SERVICE(S) 304, the data stored can vary. For example, for a database service, the data that a user inserts to the database and the associated user actions on the database service, are stored in SYNC STORE 326. In an example where the service is not a database, the recorded sync transactions would be appropriate to that service. It should be noted that some embodiments of the present invention can activate step RECORD SYNC 412 in on-line mode as a technique to record actions for activities such as, but not limited to, debug analysis.

In step PROCESS SYNC 414, if a transition from off-line mode to on-line mode event occurs, step PROCESS SYNC 414 responds that a synchronization can be performed with the connected cloud environment. From the prior SERVICE(S) 304 database service example, a user can choose to synchronize with the cloud environment and the data will be pushed to the cloud database instance operating in a similar operation that would be performed in on-line mode. Step PROCESS SYNC 414 can execute a replay of actions that were performed in the local environment in the ‘real’ cloud database instance to achieve a cloud service sync. It should be noted that an event such as, but not limited to, user interaction and/or decision to sync can be predetermined. It should be further noted that the authorization component can continue to operate during sync processing to identify issues with SERVICE(S) 304 that may have changed between sync operations.

In step DEBUG END 416, APPLICATION(S) 332 testing completes and LOCAL VIRTUAL ACCESS MODULE 322 responds by determining if a sync needs to be processed. If a sync is needed, a procedure similar to step PROCESS SYNC 414 is performed and LOCAL VIRTUAL ACCESS MODULE 322 sends a request toward TUNNEL PROCESSOR 310 to close the cloud environment connection.

Item Service_1_Package (SERVICE PACKAGE 324) 324, can be a Cloud service package where main function of the service package simulates the associated cloud service SERVICE(S) 304. Item Service_1_Package (SERVICE PACKAGE 324) 324 comprises the information and configuration of which a real cloud service (SERVICE(S) 304) operates. In on-line mode, item APP/IDE 328/330 can connect to and interact with real cloud service SERVICE(S) 304 directly through item Service_1_Package (SERVICE PACKAGE 324) 324. Item Service_1_Package (SERVICE PACKAGE 324) 324 comprises item Auth (VIRTUAL AUTH 328) 328 component(s) to communication with real cloud service (SERVICE(S) 304). Item Auth (VIRTUAL AUTH 328) 328 component can be provided by the cloud environment (e.g., AUTHENTICATION PROCESSOR 308) with “injected” authentication information using techniques such as, but not limited to, authenticated Uniform Resource Locator (URL), user/password for base authorization, client id for Oauth (e.g., “Open Authentication”) and logic to do authentication. It should be noted that Oauth is one example of a plurality of open source authentication standards. It should be noted that when in on-line mode, data and/or actions can be transferred to the cloud environment and sync data and/or actions are not required to be locally stored in a sync component (Item Sync (SYNC STORE 326) 326). It should be noted, whether in on-line or off-line mode, embodiments of the present invention, provide the ability for an application to consume cloud services outside of a cloud environment (e.g., local consumption of remote services).
